Tire traction
Tire traction can be reduced if you drive
on worn tires, tires that are improperly inflated or on slippery road surfaces.
Tires should be replaced when tread
wear indicators appear. Slow down whenever there is rain, snow or ice on
the road to reduce the possibility of
losing control of the vehicle.
Tire maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease tire wear. If you find a tire is worn uneven‐
ly, have your dealer check the wheel
alignment.
When you have new tires installed, make sure they are balanced. This will
increase vehicle ride comfort and tire
life. Additionally, a tire should always be rebalanced if it is removed from the
wheel.
Tire sidewall labeling
0+'- 







This information identifies and de‐
scribes the fundamental characteristics of the tire and also provides the tire
identification number (TIN) for safety
standard certification. The TIN can be used to identify the tire in case of a re‐
call.
1. Manufacturer or brand name
Manufacturer or Brand name is shown.
2. Tire size designation
A tire’s sidewall is marked with a tire size designation. You will need this in‐
formation when selecting replacement
tires for your vehicle. The following ex‐ plains what the letters and numbers in
the tire size designation mean.
Example tire size designation:
(These numbers are provided as an ex‐
ample only; your tire size designator could vary depending on your vehicle.)
P235/55R19 108T
P - Applicable vehicle type (tires
marked with the prefix L

this section for additional
information.
Wheel size designation
Wheels are also marked with important
information that you need if you ever have to replace one. The following ex‐
plains what the letters and numbers in
the wheel size designation mean. Example wheel size designation:
7.5JX19
7.5 - Rim width in inches.
J - Rim contour designation.
19 - Rim diameter in inches.
Tire speed ratings
The chart below lists many of the dif‐ ferent speed ratings currently being
used for passenger car tires. The speed
rating is part of the tire size designa‐ tion on the sidewall of the tire. This
symbol corresponds to that tire's de‐
signed maximum safe operating speed.
SpeedRatingSymbolMaximum Speed
S 180 km/h (112 mph)
T 190 km/h (118 mph)
H 210 km/h (130 mph) V 240 km/h (149 mph)
SpeedRatingSymbolMaximum Speed
Z Above 240 km/h (149
mph)
3. Checking tire life (TIN: Tire
Identification Number)
Any tires that are over 6 years old,
based on the manufacturing date, (in‐ cluding the spare tire) should be re‐
placed by new ones. You can find the
manufacturing date on the tire sidewall (possibly on the inside of the wheel),
displaying the DOT Code. The DOT Code
is a series of numbers on a tire consist‐ ing of numbers and English letters. The
manufacturing date is designated by
the last four digits (characters) of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT means a
plant code number, tire size and tread
pattern and the last four numbers indi‐ cate week and year manufactured.
For example:
DOT XXXX XXXX 1616 represents that
the tire was produced in the 16th week
of 2016.
WARNING
nTire age
Tires degrade over time, even whenthey are not being used.Regardless of the remaining tread,we recommend that tires be re‐placed after approximately six (6)years of normal service. Heat causedby hot climates or frequent highloading conditions can accelerate theaging process. Failure to follow thiswarning can result in sudden tirefailure, which could lead to a loss ofcontrol and an accident involving se‐rious injury or death.
4. Tire ply composition and material
The number of layers or plies of rub‐
ber-coated fabric in the tire. Tire man‐ ufacturers also must indicate the ma‐
terials in the tire, which include steel,
nylon, polyester, and others. The letter "R" means radial ply construction; the
letter "D" means diagonal or bias ply
construction; and the letter "B" means belted-bias ply construction.

NOTICE
•We recommend that when replacing tires, use the same originally supplied with the vehicles.
If not, that affects driving performance.
•When driving in high altitude grades, it is natural for the atmospheric pressure to decrease.
Therefore, please check the tire pressure and add more air when necessary.
Additionally required tire air pressure per km above sea level: 1.5 psi/km
